. OF NEW YORK, N. Y.

7 Application filed July 13, 1925. Serial No. 43,309.

To all whom it may concern:

Be it known that I, ROBERT W. HARDIE, a

citizen of the United States, and a resident of Fanwood, in the county of Union and State of New Jersey, have invented new and.

- useful Improvements in Tape-Feeding Attachments for Sewing Machines, of which the following is a specification.

This invention relates in'general to means for sewing to garment material at a single operation opposite edges of tapes having detachable fastening devices secured thereto, such as hooks and eyes, and is designed to be used with tapes having either riveted hooks and eyes, or concealed hooks and eyes attached.

The invention has for oneof its main objects to rovide a device of the character stated, that is simple in construction, effective in operation and durable in use; and one that can be readily applied to sewing machines of the standard patterns now in general use.

Attachments have heretofore been made for blind-stitch-sewing machines especially adapted for felling facings or linings on to waistbands after the buttons have been stitched in place thereon, and provided with a groove to permit the buttons to pass through while the stitching is being done.

But such attachments were used with a one needle machine making one row of stitching and were incapable of sewing both. edges of a tape having separable fasteners thereon, at a single o eration, which is one of the main objects of this invention.

With the foregoing and other objects in view herein stated, the invention consists of the. means hereinafter described, and illustrated in the accompanying drawings wherein is shown a preferred embodiment,

of the invention, but it is to be understood that changes, modifications, and alterations may be made therein without departing from the invention.

In the accompanying drawings, in which similar reference numerals indicate corresponding parts throughout the several views,

Figure 1 is a side elevation of an attachment embodying the invention, applied to tlfie bedplate of a two needle sewing mac ine.

Figure 2 is a plan view of the top of the feed attachment shown in Figure 1, with the head of the machine removed.

Figure 3 is a transverse section of the attachment taken on the line 3- -3 of Figure 2. Figure 4 is a transverse section of the attachment taken on the line 44 of Figure 2; and

Figure 5 is an enlarged view of the inlet end of said attachment. As illustrated in the drawings, 2 represents the'work table, and 3 the head of a two needle sewing machine of ordinary type, having the usual foot bar carrying a presser foot 4.

A bar 5 is connected with the usual head 6, and providedwith two sewing needles of v ordinary construction for sewing both edges of a tape 7 on to garment material at a single operation.

The tape 7 is shown provided with exposed hooks 8 riveted to the tape, which are used. to engage corresponding eyes secured to a tape sewed to another part of a garment.

Although the fasteners shown herein are what is knownas exposed hooks and eyes and are riveted to the tape, it will be understood that the attachment is equally well adapted to be used with concealed hooks and eyes sewed to a tape. 5

The tape 7 supplied to the attachment is wound upon a spool not shown, which is supported in .a bearing secured upon the underside of the work table or other part of the machine, and the tape is so wound on the spool that the face of the tape to which the fasteners are attached faces inward, so that as the tape enters the attachment the fasteners lie on the under side of the tape.

A front plate 9 is attached to the bed or work table of the machine andis preferably provided with beveled or mortised lateral edges 10, that engage corresponding edges formed at the sides of a depression formed in said bed, so that the plate will have a sliding connection with the bed, to permit its removal from the bed when desired, and

lie, with the upper surface of the plate flush with the uppersurface of the part or bed of the ma-chinejthat sustains the cloth as it is being stitched by the machine.

The front plate 9 is provided with ,an uncovered groove 11 of suflicient depth to receive th fas ene s attached to the tape,

.come caught at the entering end of the groove. The body of the tape does not pass through the groove 11 that admits of the passa e of, and guides, the fasteners, and there ore is uncovered, so that while the fasteners pass through the groove, the

lateral margins of the tape are supported by and pass over the upper surface of the plate 9, along the shoulders formed by the side walls of the groove and the adjacent portions of said plate.

Where the attachment is used to sew on I to garment material tape having eyes secured thereto, the groove 11 may be omitted, if desired, especially where concealed eyes are used, as in such cases the fastener bearing surface of the tape will lie substantially flat on to the upper surface of the plate 9, without the use of the groove.

A loop 12 is formed on the end of the front plate 9 at the entering end of the groove 11, to set the tape in alignment with the sewing needles, and hold the tape in such alignment as it passes continuously over the front plate.

After the tape passes over the top or upper surface of the front plate 9, with the fasteners facing downward, in, or over, the groove 11, the tape passes over the top or upper surface of a feed plate lying adjacent to and in substantially the same plane as that of the front plate 9, and which is provided with a groove 13 corresponding in its entering and main portions with the groove 11 of the front plate 9; but the discharge end of the groove 131s preferably curved upward as at 14, so that as the tape passes the sewing needles the inclined surface 1 1 will cause the fasteners to pass out of the groove 13.

The inlet or entering end of the feed plate is preferably provided with a loop 15 corresponding preferably with the loop 12 of the front plate 9, and said loops cooperate with each other to keep the tape in alignment with the sewing needles as the tape passes through the machine, and to that end the loops span the grooves symmetrically and extend beyond the shoulders of the grooves.

The feed plate is provided with the usual serrations 16 to cooperate with the presser foot, the usual feed dogs 17, and openings therefor, and apertures 18 for the sewing needles to enter. a

It will be seen that the lateral margins of the tape pass over and are su ported by the shoulders of the grooves o the front plate and feed plate and that the central portion of the tape passes over, but not into, the grooves of said plates, and that said central portion is supported by the fasteners 8 contacting with the bottom of said grooves.

The grooves 11 and 13 are so proportioned in width relative to the length of the hooks used, that the fastened end of the hooks is in close proximity to one wall of the grooves, and the bent-end or loop of the hooks is in'close proximity to the opposite wall of the grooves.

The said walls thereby guide the hooks as they pass through the grooves and the tape is guided by the hooks as it passes over the top of the front-plate and feed plate. In such cases the loops 12 and. 15 may be omitted.

But where concealed hooks are attached. to the tape, the tape is guided by the loops 12 and 15, and the grooves 11 and 13 may be omitted.

When the tape is placed upon the top of the plate 9, the garment material is placed over the exposed side of the tape, and brought under the needles with said tape and in the desired relation to each other.

The usual gauges or other attachments may be used in connection with the means herein shown for the purposes for which they are usually employed, and attached to the material in the usual manner.

While for most purposes I prefer to form the rear loops 15 onthe forward end of the feed plate, that is not essential, and insteadof so doing said rear loop may be formed in the rear end of the front plate.

What I claim as new, and desire to secure by Letters Patent is:

1. In a two needle sewing machine having a feed plate provided with serrated surfaces having apertures formed therein, and feed dogs engaging said apertures, means for guiding the lateral margins of a fastener bearing tape over said serrated surfaces and feed dogs, consisting of an unobstructed uncovered groove extending longitudinally of said feed plate, intermediate 2. In a two needle sewing machine having a feed plate provided with serrated surfaces having apertures formed thereinand feed dogs engaging said apertures, means for guiding the lateral marginsof a fastener bearing tape over said serrated surfaces and feed dogs, consisting of an unobstructed uncovered groove extending longitudinally of said plate, intermediate said serrated surfaces, of sufiicient depth to permit the unobstructed passage therethrough of fasteners secured to said tape, and having side walls adapted to guide said :fasteners through sa d groove, and a slidable plate mounted in advance of the feed plate and provided with a groove in line with the groove of the feed spanning said groove symmetrically, and extending beyond the shoulders of said groove.

plate and with a loop 10 ROBERT W. HARDIE.
